中文说明：随机调制信号下的模拟ppm，用MATLAB实现的压缩传感，包括脚本文件和函数文件形式，IDW距离反比加权方法，可以得到很精确的幅值、频率、相位估计，最终的权值矩阵就是滤波器的系数。
English Description：
Random modulation signal simulation ppm, for compressed sensing using MATLAB to achieve, including scripts and functions file form, IDW inverse distance weighting method can be very accurate amplitude, frequency and phase estimation is obtained and the final weight matrix is that of the filter coefficients.
